but I’ve rarely seen it discussed much or sold for any premium like the digglet 90 degrees fight symbol error.
Looking at online videos it seems this is a pretty common corrected error as I’ve seen it on a lot of machamps. The four fists are slightly to the right of the circles they’re in.
Worth anything?
No one cares for Machamp
This is not the kind of error that people find interesting or valuable. I believe it also affects all shadowless versions of the card, meaning it is just the de facto version of it.
I really think this forum needs an “is my error card valuable” megathread.
well then 
You can catch all four of these hands
ok thanks, was pretty sure it wasn’t a big error as I’ve seen so many online not even acknowledging it, a few of my other cards also have the fight symbol shift right
My borders on that card are also not quite yellow, but not really brownish gold, so I think it’s either faded or not the actual golden border machamp, which also may not be valuable. My shadowless electabuzz is brown for sure though, way different than regular yellow wotc, but might be all shadowless, also probably not valuable.
A thread would be cool.
Be the change you want to see
And whenever someone posts, a bot automatically responds with “no”
no rarity 
Perfect. We have solved the problem completely.
Machamp has enough elbow grease on hand to take care of himself.
Four elbows to be specific
